Swan no Baka

Swan no Baka(スワンの馬鹿！)

40-year-old Daisuke SUWANO tries so hard to keep up his image as "Best Father" "Best Husband" and "Best Boss" in front of his staff who respect and admire him. In spite of his cool and generous appearance, he locks himself up in a bathroom to count how much money he can spend till the next payday. His wife allows him to use only 30,000 (US$270) a month, which is almost impossible to survive, but that's actually the average allowance a Japanese husband gets. Daisuke feels he's just like a swan; swimming on the water so elegantly while struggling desperately under the water. (Source: Drama Wiki)
